Product Overview

Frequency Response (at 1 kHz, channel controls centered): 50 Hz to 20 kHz +/- 2 dB; -3 dB corner at 25 Hz
Total Harmonic Distortion: <0.1% at +4 dBu output level, 50 Hz to 20 kHz (through 22 Hz to 22 kHz filter; Input at 12 o' clock and Master at 12 o' clock, all other controls full counterclockwise)
Hum and Noise (150 ohm source; through 22 Hz to 22 kHz filter): Equivalent Input Hum and Noise: 123 dBV max., 125 dBV typical
Output Hum and Noise (channel controls full counterclock-wise): Master full counterclockwise: 90 dBV: Master full clockwise: 70 dBV
Common Mode Rejection: >70 dB at 1 kHz
Polarity: All inputs to all outputs are non-inverting
Input Channel Activation: Attack Time: 4 ms; Hold Time: 0.4 s; Decay Time: 0.5 s
Off-Attenuation: 13 dB
Overload and Shorting Protection: Shorting outputs, even for prolonged periods, causes no damage. Microphone inputs are not damaged by signals up to +10 dBV (3V)
Equalization: Low-frequency: 6 dB/o
